Wet-Chemical Synthesis of ZnTe Quantum Dots
ZnTe quantum dots (QDs) have been very attractive because of their potential applications in optoelectronic devices operating in the blue-green region of the spectrum. This paper describes a convenient one-step synthesis of high-quality ZnTe QDs in high-temperature organic solution with high yield. Anhydrous zinc chloride was dissolved in phenyl ether under argon protection and oleic amine was ...
متن کاملHigh temperature acidic oxidation of multiwalled Carbon nanotubes and synthesis of Graphene quantum dots
The acid oxidation of carbon nanotube generally results in opening the close ends of the nanotube and to make surface modifications. Herewith, Multiwall carbon nanotubes (MWCNTs) were oxidized in acids at high temperature experimental conditions which led to the formation of graphene quantum dots (GQDs). High resolution transmission electron microscope (HRTEM), energy dispersive X-ray spectro...

متن کاملFabrication of silicon quantum wires by anisotropic wet chemical etching and thermal oxidation
Ultrafine silicon quantum wires with high-quality Si/SiO2 heterointerfaces are successfully fabricated by utilizing anisotropic wet chemical etching and subsequent thermal oxidation. It is also found that the lateral dimensions of silicon quantum wires can be well controlled by selecting the temperature of the thermal oxidation process. The cross-sectional image from a scanning electron microsc...
متن کاملHybrid electrochemical/chemical synthesis of quantum dots.
The "electrochemical/chemical method" (or "E/C method") is a new wet chemical method for synthesizing semiconductor quantum dots on graphite surfaces. The E/C synthesis of quantum dots composed of the generic semiconducting salt, MX, typically involves three steps: (1) electrochemical deposition of nanoparticles of the metal, M degrees, from a solution of metal ions, M(n)(+); (2) electrochemica...
